Voice Actor Comments
Akaji Riko (as Isshiki Rinna Milford)
During recording, there were moments when I unexpectedly discovered new angles of myself without meaning to. Meeting new people and learning about yourself in new ways is something truly precious. Seeing Rinna — who was always so tough and brave — slowly grow and encounter “love” through her relationship with Mechi made me feel that even more deeply. For me, Rinna is a character who makes me genuinely want to play the role that bears her name. I hope everyone will join her on her journey to happiness!
Umeda Shuichiro (as Rokutanda Mechi)
I’m thrilled to be a part of the “Isshiki-san wa Koi wo Shiritai.” anime! I was so happy to get the role of Mechi — from the very first recording session, the atmosphere in the booth was wonderful, and it felt like the team had been working together all season already. I think that energy is a real strength of “Isshiki-san.” I hope to deliver the fun, heart-pounding moments between Rinna and Mechi to every fan!
